OUTLET-CLOSING DEVICE FOR HOSE-NOZZLES.

SPECIFICATION forming part of Letters Patent No. 565,290, dated August4, 1896. Application filed October 8, 1895. fierial No. 564,982. (Nomodel.)

To aZZ whom it may concern:

Be it known that 1, JOHN H. MELAVIN, of Cambridge, in the county ofMiddl'esex and State of Massachusetts, have invented certain new anduseful Improvements in Outlet-Closing Devices for Hose-Nozzles, 850., ofwhich the following is a specification.

This invention relates to means for closing and opening outlets ofhose-nozzles, beerbottles, (he. and it has for its object to provide asimple and durable device, free from liability of leakage and requiringno packing or close fitting, whereby an outlet may be tightly closed andreadily opened.

The invention consists in the novel features of construction andrelative arrangement of parts hereinafter fully described in thespecification, clearly illustrated in the drawings, and particularlypointed out in the claims.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a sectional view of a hose-nozzle provided with aclosing device embodying my invention, the valve being closed. Fig. 2represents a side view of the same, the valve being opened. Fig. 3represents a modification.

The same letters of reference indicate the same parts in all thefigures.

In the drawings, a represents a neck havin g a dischargeorifice a, saidneck being here shown as a part of a hose-nozzle.

Z) represents a lever pivoted at c to the nozzle. To one end of thelever 17 is connected a valve d, formed to close the orifice a. Theother end of the lever projects outwardly from thenozzle, as shown.

f represents a collar which is rotatively mounted on the neck a and ispreferably engaged therewith by means of screw-threads formed on theneck and in the collar, the said engagement being sufficientlyfrictional to hold the collar at any position to which it may be turnedand prevent it from turning loosely on the neck. The collar has acamshaped edge f, against which the outer portion of the lever 19 bears,said edge being curved or inclined, as shown, so that by rotating thecollar the portion of the lever bearing thereon will be raised ordepressed, as the case may be.

Then the collar is in the position shown in Fig. 1, it holds the leverin position to close the valve, and when the collar is in the positionshown in Fig. 2 it permits the valve to open. The collar may be movedsufficiently to only partially open the valve, causing a narrow annularopening between the valve and its seat, so that the liquid will bescattered or sprayed.

It will be seen that the collar fiwith its cam-shaped curved edge,constitutes an adjustable stop adapted to hold the valve-controllinglever in diiferent positions. The lever and the adjustable stop are bothsupported on external portions of the neck, so that no care is necessaryto prevent leakage excepting between the valve and its seat. Hence thecost of making the device is comparatively small.

The Valve (Z is preferably'made of or surfaced with rubber or othersuitably-yieldin g material.

I do not limit myself to the screw-thread connection between the collarf and the nozzle or neck a, as the collar may be fitted to turn upon theneck between suitable stops.

Fig. 3 shows a modification in which the adjustable stop is a screw g,working in a tapped orifice in an arm h on the nozzle a, the screw beingarranged to press against the outer arm of the lever b and force thevalve to its closed position. When the screw is retracted, the valve isreleased.

Having thus explained the nature of my invention and described a way ofconstructing and using the same, though without attempting to set forthall of the forms in which it may be made or all of the modes of its use,what I claim, and desire to secure by Letters Patent, is-- 1. A nozzleor neck having a dischargingorifice; a lever pivotally connected withthe nozzle, the inner end of the lever being formed to project over themouth of the nozzle,while its outer end extends outwardly from thenozzle; a valve secured to the inner end of the lever and adapted toentirely close the nozzle; and a stop adjustably connected with thenozzle, said stop being movable to close the valve through the lever andto permit the removal of the valve from the path of a stream issuingfrom the nozzle.

2. A nozzle or neck having a discharging- In testimony whereof I havesigned my orifice, a lever pivotally connected with the name to thisspecification, in the presence of IO nozzle, a valve supported by thelever and two subscribing witnesses, this 30th day of adapted to openand close the orifice of the August, A.
